Abstract

1428747 Films containing glass microbeads IMPERIAL CHEMICAL INDUSTRIES Ltd 10 July 197.4 [7 Aug 1973] 37368/73 Headings C3P and C3R Self-supporting films are made of synthetic polymeric materials containing 0À01 to 5% by weight of the polymer of glass microbeads having a weight average particle diameter not exceeding 35 microns. The beads may be hollow or preferably solid beads of alkali metal silicate glass. The polymer may be a polycarbonate, polyester, polysulphone, polyamide or polyolefin; and the compositions may also contain ethoxylated C 12-22 aliphatic amines, fatty acid amides and glycerides, and may be formed into films by blow extrusion methods. The films may be coated with polymeric materials or metallized, and used in packaging and as dielectric spacers in capacitors. Examples describe the preparation of films from compositions of glass microbeads and (2, 3 and 4) polypropylene, (5 and 6) propylene/ethylene block copolymer and (7) polyethylene terephthalate.
